Problem 2225. Three...is a magic number.

To help you get rid of that earworm, here's a new Cody problem. You are given a square matrix containing positive integers. We want to determine if there are three consecutive occurrences of the same number in a row or column. For example:

1 1 1
4 2 3
2 3 4

Should be marked "true" because there are three consecutive ones in the first row. Likewise

5 2 3
5 3 2
5 4 1

should also be marked "true" because there are three consecutive fives in the first column. However:

5 2 3
3 5 2
1 4 5

Is false, as we do not care about the three consecutive fives along the trace of the matrix. The matrix will always be at least 3x3, but they can be larger. Good luck!
